Pramipexole Versus Placebo in PD Patients With Depressive Symptoms - Full Text View

ClinicalTrials.gov Identifier:	NCT00297778

Purpose

Parkinsons Disease (PD) is caused by a decrease of dopamine in a particular part of the brain. Dopam ine is a messenger substance (neurotransmitter) that is used by the cells of the brain (nerve cells) to control and harmonize muscle movements. Consequently, the main manifestations of the disease aff ect movement and include tremor, muscular rigidity, slowness in performing movements and loss of bal ance. However, the disease affects also other, non motor functions and may cause other disorders, such as depression. Depression may be a reaction to the disability caused by the disease, but many studies show that depression is more common in PD than in other chronic debilitating illnesses. Moreover, there is also a biological explanation for the phenomenon: dopamine is also used in brain circuits in volved in the experience of pleasure, and loss of pleasure in daily physical or social activity is o ne of the key manifestations of depression. The objective of the study is to assess whether pramipexole, at doses approved for the treatment of PD symptoms, is more effective than placebo in resolving depressive symptoms in PD patients.

Also data on the safety of the product in the disease will be collected.

Primary Outcome Measures:

Change From Baseline in the Beck Depression Inventory-Version 1A (BDI-IA) Total Score at Week 12 [ Time Frame: Baseline and Week 12 ]
The BDI measures symptoms of depression on an ordinal scale ranging from 0 (no symptoms) to 63 (worst symptoms)

Secondary Outcome Measures:

BDI-IA Clinical Response at Week 12 [ Time Frame: Week 12 ]
BDI clinical response was defined as a reduction of ≥50% from baseline
Change From Baseline in the Geriatric Depression Scale-Short Form (GDS-SF) Total Score at Week 12 [ Time Frame: Baseline and Week 12 ]
The GDS measures symptoms of depression on an ordinal scale ranging from 0 (no symptoms) to 15 (worst symptoms)
Change From Baseline in Snaith-Hamilton Pleasure Scale (SHAPS) Total Score at Week 12 [ Time Frame: Baseline and Week 12 ]
The SHAPS measures anhedonia (inability to experience pleasure) on an ordinal scale ranging from 0 (no anhedonia) to 14 (worst anhedonia)
Change From Baseline in the Unified Parkinson's Disease Rating Scale (UPDRS) Part I Depression Score at Week 12 [ Time Frame: Baseline and Week 12 ]
The UPDRS part I depression score measures depression on an ordinal scale ranging from 0 (none) to 4 (sustained depression/suicidal thoughts)
Change From Baseline in the UPDRS Part II Total Score at Week 12 [ Time Frame: Baseline and Week 12 ]
Unified Parkinson's Disease Rating Scale part II total score on FAS The UPDRS part II total score measures the impact of PD on activities of daily living on an ordinal scale ranging from 0 (normal) to 52 (worst symptoms)
Change From Baseline in the UPDRS Part III Total Score at Week 12 [ Time Frame: Baseline and Week 12 ]
The UPDRS part III total score measures the impact of PD on motor skills on an ordinal scale ranging from 0 (normal) to 108 (worst symptoms)
Change From Baseline in the UPDRS Part II+III Total Score at Week 12 [ Time Frame: Baseline and Week 12 ]
The UPDRS part II+III total score measures the impact of PD on activities of daily living and motor skills on an ordinal scale ranging from 0 (normal) to 160 (worst symptoms)
Clinical Global Impressions of Global Improvement (CGI-I) at Week 12 [ Time Frame: Week 12 ]
The CGI-I measures the overall improvement in the participants condition from baseline on an ordinal scale ranging from 1 (very much improved) to 7 (very much worse)
Change From Baseline in the Parkinson's Disease Questionnaire-39 (PDQ-39) Overall Index Score at Week 12 [ Time Frame: Baseline and Week 12 ]
The PDQ-39 measures aspects of health in PD participants, the overall index score is the mean of the eight individual domian scores measured on a continuous scale ranging from 0 (no problem at all) to 100 (maximum level of the problem)
Change From Baseline in the European Quality of Life Scale (EUROQOL (EQ)-5D) Overall Index Score at Week 12 [ Time Frame: Baseline and Week 12 ]
The EQ-5D measures health status on a continuous scale ranging from 0 (dead) to 1 (full health)
Change From Baseline in the European Quality of Life Visual Analogue Scale (EUROQOL (EQ) VAS) Score at Week 12 [ Time Frame: Baseline and Week 12 ]
The EQ-VAS is a self rating of current health-related quality of life measured on a continuous scale ranging from 0 (worst imaginable health state) to 100 (best imaginable health state)
